The World's Most Popular Bookcase: Best Uses of the IKEA Expedit

If you love looking at pictures of interiors like we do, you'll probably see a few of the same pieces crop up over and over, design classics like the Eames lounge or Harry Bertoia's wirechairs. But one of the most ubiquitous pieces has a humbler pedigree (and a much lower price point). It's the IKEA Expedit, and it's taking the world of storage by storm.

The genius of the Expedit is in its simplicity — the deep square shelves make it suitable for storing practically anything, and the extra thickness of the outside frame gives the unit a pleasingly solid appearance that belies its low price tag.

The simple design, and the fact that the shelving units come in a huge variety of sizes — 2x2, 2x4, 4x4, 5x5 — make the Expedit adaptable to many different kinds of spaces, and almost infinitely hackable. Below are some of our favorite Expedit spottings from our Apartment Therapy house tours, and from all over the web.
